Bernie Siebers
Daniel was thorough, knowledgeable and personable. What more could I ask?
Paul Macko
Alberto M is a fantastic asset to Princeton Air. He always puts the customer first, explains everything well, and is very thorough.
Anthony Scardella
Install of new HVAC system went very smoothly. Technicians were on time, respectful of any potential mess they might make and were very personable. Would definitely recommend.
Mindy May
We moved into a new home and had no idea about the heating system. The technician. Dominic, took time to show us the system and made good recommendations.
Now 6 months later we had Maurice Gaines technician, come do a maintenance check on our air conditioner. He found a problem and fixed it immediately. Now the unit will run smoother and is in good working order
We now feel we have good knowledge of the workings and look forward to working with Princeton Air for our future needs.
Charles Psemeneki

Came out to see what my problem was right away. Great service. They are my new AC go to.
Daniel Lavery
After setting up an emergency appointment on line within one day, Princeton Air sent their technician Tom, who diagnosed the problem and ordered the replacement part. Tom came back three business days later and replaced the part (which was under warranty) and the system is now working fine.
K G
Shout out Ryan for quickly diagnosing and repairing a bad contactor on my unit. Walked me through the repair, was detail oriented, and provided guidance on future considerations.
Bob Ambielli
Service rep stayed until issue was resolved!!
Barbara Spring
Starting with Ryan Gobel who diagnosed the problem almost immediately. Attempted to repair. But the AC was not cooperating. Coolent was the issue. Ryan explained in detail of what was going on with the AC. I made the decision to replace the AC and while I was at it to replace the furnace also. The technicians that replaced the equipment were professional and worked very hard at completing the job in a timely manner. They cleaned up behind themselves. Left my garden outside in perfect order. My overall experience with Princeton Air worked well with me and I would highly recommend.
Judy Considine
